दम्भो दर्पोऽभिमानश्च क्रोधः पारुष्यमेव च। अज्ञानं चाभिजातस्य पार्थ सम्पदमासुरीम् ॥

dambho darpo ’bhimānaśh cha krodhaḥ pāruṣhyam eva cha ajñānaṁ chābhijātasya pārtha sampadam āsurīm

Hypocrisy, arrogance and conceit, wrath and also harshness and unwisdom are his who is born, O Pârtha, with demoniacal properties.

In plain words: Krishna tells Arjuna the qualities of a person born with demonic, or harmful, nature: faking goodness, arrogance, being full of oneself, anger, harshness, and foolishness.
